Dear members.\
I have been experiencing some very erratic behavior on my VT unit
on an INOVA 400 system. Finally I have come to the conclusion after
plenty of trouble shooting that whenever the VT airflow ( N2 )
exceeds 10 liter per minute the RTD resistance jumps all over the
place. This in turn triggers the control unit to shut the heater
down. I bench checked both probes I have for this system and both
act the same way. has anyone else observed this problem ? Paul
